CLion: Jom (parallel builds) and clcache (fast partial builds, faster than VS2017)

• CLion Jom (parallel builds):
  • Settings, Build.../Toolchains, Make = path/to/jom.exe

---

clcache may cause invalid builds. https://github.com/frerich/clcache/issues/315

• CLion clcache (lightning-fast partial builds):
  • Settings, Build.../Toolchains
  • C Compiler = path/to/clcache.exe
  • C++ Compiler = path/to/clcache.exe
• To enable clcache server (otherwise uselessly slow):
  • Settings, Build.../CMake. For each of Debug/Release/etc, click Environment [...] button.
  • CLCACHE_SERVER=1 and CLCACHE_HARDLINK=1 (skip CLCACHE_HARDLINK if j0CC is cloned to different partition from your %userprofile% homedir).
  • Before building, execute python-dir\Scripts\clcache-server.exe.
• OUTDATED SCREENSHOT (easier to set compiler on Toolchains tab, instead of per-profile variables[1]):

Regular clcache may enter an infinite loop. I've patched it for myself (not in repo).
